- Define the term neohormones
- Identify the class of vertebrates in which neohormones evolved
- Identify three neohormones essential for lactation
Abstract
As mammals evolved, so did a unique set of hormonal systems designed to meet the complex demands of pregnancy, birth, and lactation. The development of the placenta and the need to nourish highly dependent offspring through milk led to the emergence of specialized hormones now referred to as neohormones.
These hormones are fundamental to mammalian reproductive success. They not only regulate fertility and pregnancy but also direct the development and function of mammary tissue and contribute bioactive components to human milk. Beyond their immediate physiological roles, neohormones interact with the epigenome, modulating gene expression in ways that influence growth, development, and long-term health outcomes for both parent and infant.
This session explores the evolutionary origins and biological significance of neohormones, highlighting their roles in pregnancy, lactation, and early life programming. Participants will examine key neohormones involved in mammary function and human milk production, as well as emerging research on their broader impact on health, development, and fertility.
By deepening understanding of these powerful hormonal systems, attendees will gain a more integrated view of lactation biology and its critical role in supporting optimal outcomes across the lifespan.
